Emma S J Robinson
Mood disorders represent one of society's most costly and challenging health burdens. The drug treatments used today were initially discovered serendipitously in the 1950s. Animal models were then developed based on the ability of these drugs to alter specific behaviours. These models have played a major role in the development of the second generation of antidepressants. However, their use has been heavily criticized, particularly in relation to whether they recapitulate similar underlying biology to the psychiatric disorder they are proposed to represent...

Engineering chemical entities to modify how pharmaceutical targets function, as it is done in drug design, requires a good understanding of molecular recognition and binding. In this context, the limitations of statically describing bimolecular recognition, as done in docking/scoring, call for insightful and efficient dynamical investigations. On the experimental side, the characterization of dynamical binding processes is still in its infancy. Thus, computer simulations, particularly molecular dynamics (MD), are compelled to play a prominent role, allowing a deeper comprehension of the binding process and its causes and thus a more informed compound selection, making more significant the computational contribution to drug discovery1...

Diabetes is a metabolic syndrome increasing rapidly due to occupational stress, lack of physical activity, sedentary lifestyle and increasing occurrence of obesity, associated with rapidly growing urbanization and industrialization. Due to erroneous carbohydrate metabolism, diabetics are more prone to chronic complications like nephropathy, neuropathy, retinopathy, coronary artery disease and peripheral arterial disease resulting in tissue damage. Current treatment protocols to these problems produce more serious adverse effects and are costly too...

BACKGROUND: Cost-effectiveness analysis (CEA) estimates can vary substantially across patient subgroups when patient characteristics influence preferences, outcome risks, treatment effectiveness, life expectancy, or associated costs. However, no systematic review has reported the frequency of subgroup analysis in CEA, what type of heterogeneity they address, and how often heterogeneity influences whether cost-effectiveness ratios exceed or fall below conventional thresholds. METHODS: We reviewed the CEA literature cataloged in the Tufts Medical Center CEA Registry, a repository describing cost-utility analyses published through 2016...

This report describes the design and evaluation of phosphorylated 7-ethyl-10-hydroxycamptothecin (SN38-P), which selectively eliminates tumor-forming proliferative stem cells, including human induced pluripotent stem cells (hiPSCs) and neural stem cells, from iPSC-derived neural cell mixtures. Results of the present study demonstrate that simple phosphorylation of an anticancer drug can provide a safe, cost-effective, and chemically-defined tool for decontaminating hiPSC-derived neuron.

AIM: Phloroglucinol is a musculotropic anti-spasmodic drug. It is frequently prescribed in many European countries with a considerable cost for health services. The purpose of this study was to review the existing randomised controlled trials (RCT) comparing the efficacy of phloroglucinol treating abdominal pain versus placebo. METHODS: A literature search was carried out up to May 2017 to select RCT comparing the effect of phloroglucinol versus placebo with intensity of abdominal pain as an endpoint...

Continued development of existing drugs ('drug rediscovery') may offer new therapeutic options and be cost-effective. Rediscovered drugs are commonly prescribed off-label, although licensing can be important to allow safe and controlled prescription of the drugs to patients. Licensing of a new indication for a generic drug, however, is a complicated process since there is no blueprint for this and there is little interest from the pharmaceutical industry due to an unattractive cost-recovery model. In this article, we illustrate the successful license-extension for thioguanine - initially developed in 1950 for leukaemia - as a new treatment for patients with inflammatory bowel disease...

Studying how and where drugs are metabolized in the brain is challenging. In an entire organism, peripheral metabolism produces many of the same metabolites as those in the brain, and many of these metabolites can cross the blood-brain barrier from the periphery, thus making the relative contributions of hepatic and brain metabolism difficult to study in vivo. In addition, drugs and metabolites contained in ventricles and in the residual blood of capillaries in the brain may overestimate drugs' and metabolites' concentrations in the brain...

Over the years, the pharmaceutical industry has been at the forefront of research and innovation in drug discovery and development. The process of drug discovery extending from pre-clinical studies to multi-centric clinical trials and post-marketing phase is a costly affair running into billions of dollars. On the flip side, not all investigational molecules clear the trial phases and get approved; which puts pressure on the manufacturers to maximise the profit from approved drugs. It is in this key area, the practice of drug promotion plays its role...

A majority of breast cancers are hormone receptor (HR) positive and are responsive to various types of hormone manipulation. Endocrine therapy is the preferred first-line therapy for patients with advanced estrogen receptor (ER) positive, HER2-negative breast cancer who do not have symptomatic visceral disease. Endocrine therapy is often continued in the second- and third-line setting, with chemotherapy deferred until tumor becomes endocrine therapy refractory and/or a visceral crisis in imminent. Therapeutic options vary based on clinical presentation and include single-agent therapies such as tamoxifen, aromatase inhibitors and fulvestrant, and combination therapies options...

BACKGROUND AND OBJECTIVE: Type 2 diabetes mellitus (T2DM) is frequently associated with co-morbidities that exacerbate cardiovascular (CV) risk. CV disease is the leading cause of death in people with diabetes across the world and accounts for approximately half the deaths in the T2DM population. Hence, the objective of present study was to evaluate the cost-effectiveness of empagliflozin, in addition to standard of care (SoC), for the treatment of adult patients with T2DM and high CV risk in Greece...

To face the high costs of developing new drugs, researchers in both industry and academy are looking for ways to repurpose old drugs for new uses. In this sense, bisphosphonates that are clinically used for bone diseases have been studied as agents against Trypanosoma cruzi, causative parasite of Chagas disease. In this work, the development of first row transition metal complexes (M = Co2+, Mn2+, Ni2+) with the bisphosphonate ibandronate (iba, H4iba representing the neutral form) is presented. The in-solution behavior of the systems containing iba and the selected 3d metal ions was studied by potentiometry...

Background: One of the prevailing otologic infections in our country is chronic suppurative otitis media, especially the tubotympanic type for which various treatment protocols are followed. Usually, oral and topical antibiotics (mainly quinolones) are given alone or in combination. There is a lack of consensus as to whether topical drops alone are effective or a combined oral and systemic therapy should be prescribed. In our study, we have attempted to observe the efficacy of empirical therapy with combined ciprofloxacin versus topical drops only in patients with tubotympanic chronic suppurative otitis media for control of infection...

The question of whether signaling bias is a viable discovery strategy for drug therapy is discussed as a value proposition. On the positive side, bias if easily identified and quantified in simple in vitro functional assays with little resource expenditure. However, there are valid pharmacological reasons why these in vitro bias numbers may not accurately translate to in vivo therapeutic systems making the expectation of direct correspondence of in vitro bias to in vivo systems a problematic process. Presently, in vitro bias is used simply as a means to identify unique molecules to be advanced to more complex therapeutic assays but from this standpoint alone, the value proposition lies far to the positive...

A dozen or more regulatory frameworks have been proposed for legal cannabis but many of the "not-for-profit" options have yet to be developed in any detail, reducing the likelihood they will be seriously considered by policy makers. New Zealand's innovative "not-for-profit" regulatory regime for gaming machine gambling (i.e. "slot machines") has reversed the previous increase in gambling expenditure, empowered local councils to cap the number of gambling venues, and is unique in requiring the societies operating gaming machines to distribution 40% of the gross expenditure from machines (i...

Symmetry-adapted perturbation theory (SAPT) is a valuable method for analyzing intermolecular interactions. The functional group SAPT partition (F-SAPT) has been introduced to provide additional insight into the origins of noncovalent interactions. Until now, SAPT analysis has been too costly for large ligand-protein complexes where it could provide key insights for chemical modifications that might improve ligand binding. In this paper, we present a large-scale implementation of F-SAPT which is especially efficient when one of the interacting monomers is significantly larger than the other, as is usually the case for drug-protein interactions...

Chuanwei Xin, Zhu Dong, Mengmeng Lin, Gong-Hua Li
Background: The prescriptions of proton pump inhibitors (PPIs) have raised concern due to both huge increase in medical expenditure and the possible long-term adverse events caused by them; therefore, an approach to taper off the irrational use of PPIs by patients is clinically warranted. The aim of this study was to evaluate the impact of pharmaceutical interventions on the rational use of PPIs. Patients and methods: A single-center, pre- to post-intervention study (pharmaceutical interventions group and control group) was performed in a Chinese hospital...

BACKGROUND: The evolution of technology in healthcare has increased the health care's costs and, the universal healthcare systems, in developed countries, need to ensure proper allocation of resources. Thus, the major issue is assessing the effectiveness of new medical technologies. The evaluation of quality of life in response to new treatments has become a key indicator in chronic conditions for which medical interventions are evaluated not only in terms of increasing the number of expected life years but also in terms of increasing quality of life...
